Abstract
The utility model provides a hydraulic support leg device used for a concrete conveying pump, which is provided with a pump bracket. Telescopic support legs are arranged at two sides below the front end and the rear end of the pump bracket, counterweight balance carrying bridge wheels are arranged at two sides below the middle of the of the pump bracket, two pump main cylinders are arranged in middle of the bridge wheel, a vertical cylinder for vertically lifting the concrete conveying pump is arranged in middle of the two pump main cylinders, and communicated with the pump main cylinders by pipelines. In the utility model, the vertical cylinder is arranged in middle of the main cylinders of the pump bracket, when the pump needs to be lifted, a manual directional valve handle is wrenched left and right, then the vertical cylinder can be lifted automatically, so that the time for supporting the pump by a jack lift manually is saved, and the purposes of emplacing and retracting the pump can be achieved.
Description
Technical field
The utility model relates to a kind of hydraulic leg device that is used for concrete pump.
Background technology
The holder formula pump that uses at present is provided with 2 haul bridge wheels, 4 supporting legs (each 2 of front and back).When pump emplaces, take manual work to utilize jack to rise the pump housing (heavy 6T is many for pump) and extend, fix 4 supporting legs (be called and rise pump), in the time of withdrawing from pump; Fall pump again earlier, supporting leg is regained, must still utilize jack that the pump housing is risen with manual work as rising the pump program; Regain supporting leg then; Pump just can move, and such program is loaded down with trivial details, take the people, bothersome, dangerous again, therefore is necessary to improve.
The utility model content
The technical problem that the utility model solves: a kind of hydraulic leg device that is used for concrete pump is provided; In the middle of the master cylinder of pump machine carriage, a vertical oil cylinder is set, when needs up-down pump machine, pulls the hand-operated direction valve handle about needing only; Just can be with vertical oil cylinder automatic lifting; Pump can automatic lifting, has saved the artificial time of propping up pump with jack, reaches conveniently the purpose that emplaces, withdraws from pump.
The technical scheme that the utility model adopts: the hydraulic leg device that is used for concrete pump; Has pump machine carriage; Both sides, below, said pump machine carriage front and back end are equipped with telescopic supporting leg, and both sides, middle below are provided with counterweigh delivery bridge wheel, are provided with two pump machine master cylinders in the middle of the said bridge wheel; Is provided with vertical oil cylinder in the middle of the said two pump machine master cylinders, and vertical oil cylinder and pump machine master cylinder are through the pipeline connection with the concrete pump vertical lift.
Further, said vertical oil cylinder is fixed on the pump machine carriage and adopts the hydraulic system of pump machine gear pump to realize automatic vertical lift, is connected with pressure meter, superposing type overflow valve and hand-operated direction valve in turn between gear pump and the vertical oil cylinder.
The utility model is compared with prior art simple in structure, and is easy to use, has the automaticity height, can reduce operator's labour intensity, increases the reliability of equipment, the advantage of enhancing productivity simultaneously.

Fig. 2 is the utility model structure side view;
Fig. 3 is the hydraulic control system schematic diagram of the utility model.
The specific embodiment
A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1,2,3.
The hydraulic leg device that is used for concrete pump; Has pump machine carriage 1; Both sides, below, said pump machine carriage 1 front and back end are equipped with telescopic supporting leg 2, and both sides, middle below are provided with counterweigh delivery bridge wheel 3, are provided with two pump machine master cylinders 5 in the middle of the said bridge wheel 3; Be provided with vertical oil cylinder 4 in the middle of the two pump machine master cylinders 5, and vertical oil cylinder 4 is connected through pipeline with pump machine master cylinder 5 with the automatic lifting of concrete pump vertical lift.Vertical oil cylinder 4 is fixed on the pump machine carriage 1 and adopts the hydraulic system of pump machine gear pump 6 to realize automatic vertical lift, is connected with pressure meter 7, superposing type overflow valve 8 and hand-operated direction valve 9 in turn between gear pump 6 and the vertical oil cylinder 4.
Operating principle: when needs ascending, descending pump machine, pull the handle 10 of hand-operated direction valve 9 about needing only, just can be with vertical oil cylinder 4 automatic lifting; The weight of vertical oil cylinder 4 jack-up can reach 30 tons, through newly-increased pressure meter 7 and superposing type overflow valve 8, (the setting operating pressure is 12Mpa); Through switching-over about hand-operated direction valve 9; Make vertical oil cylinder 4 automatic vertical lifts, and be balance pivot, the flexible purposes of 4 supporting legs 2 before and after realizing with pump machine bridge wheel 3.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
